yarn application stops when uid is too low

hi all,

Just want to share the experience when the min.user.id has not changed by default, no yarn application could be submitted. Usually, you will have something like below.

Diagnostics: Application application_1500628462670_0096 initialization failed (exitCode=255) with output: main : command provided 0

main : run as user is hiuy

main : requested yarn user is hiuy

Requested user hiuy is not whitelisted and has id 501,which is below the minimum allowed 1000

Failing this attempt. Failing the application.

 ApplicationMaster host: N/A

 ApplicationMaster RPC port: -1

 queue: root.users.hiuy

 start time: 1500632228942

In order to solve the problem, you could either bump up the UID for the yarn application user to any integer value that above 1000, or you could set the min.user.id at YARN configuration. Make sure that you need to restart YARN when after the configuration alteration is done.

Hope that helps. Thanks!
